I used a textured card and punched a variety of shapes to try out. The dark patches on the card are because this is after they have been used with the clay.
this butterfly paper punch.
flower punch for this one and added detail with my craft pick.
So If you like to play with polymer clay and you have some paper punches, then give this a try. It's great fun. I'll show you some of the buttons and card embellishments I've been making very soon.
